ADVANCED AUDIO FILTERING FOR R21 USING MACHINE LEARNING
Rickel, Jodi Luise
The goal: To expedite cleaning of maritime distress signals without manual filtering.
Maritime distress transmissions received by the U.S. Coast Guard are subject to environmental
noise and communication channel distortion, and must be filtered manually using current
Rescue 21 software, which can be time consuming and imprecise.
This project uses deep learning to improve signal filtration. The core of the software is a denoising auto-encoder, a machine learning model that recognizes and removes distortion from
input audio files. Noisy distress signals are input into the team’s software and automatically
filtered by the auto-encoder, which generates a coherent, noiseless version of the input signal.
Testing required the software to process a 5-minute audio segment in under a minute while using less than 2 GB of local memory. The software is compatible with all operating systems used by the Coast Guard, including the existing Rescue 21 software.

BEFORE THE SUN SETS: A CREATIVE ACCOUNT
Wilson, Steven Jack
Using creative non-fiction, this piece explores and follows the life of a person
experiencing dual sensory loss of hearing and sight. This narrative is through the lens of seeing
both, the positives and negativesj of the medical community, paradigm and influences. Also, this
piece explores the lifelong experiences of a person who’s worked with individuals in the
audiology field since he was a young boy, to an older man.
This piece investigates the damaging affects others create by ostracizing whether
knowingly or not. Marginalization comes in many forms and can happen to anybody, at any age.
This exploration of self by this author strives to tell his story in a unique way.

Get Up and Get Moving: Cardiovascular Benefits For Short Bouts of High Intensity Exercises
White, McKenna Lauren
“Over 340 million children and adolescents worldwide aged 5-­‐19 were overweight or obese in 2016.”(1) Becoming obese or overweight can lead to cardiovascular issues that can affect the heart, the blood, or vessels. The heart, blood, and vessels have very important functions for the body and exercising can help improve their functions. Most importantly, short bouts of high intensity exercise is proven to be very beneficial. This type of exercise not only improves cardiovascular health, but it also gets people up and moving. A daily exercise flipbook is attached to encourage the youth and adults to partake in daily physical activity for at least two minutes a day. Its purpose is to reveal how high intensity physical activity can benefit the cardiovascular system and in hopes, reduce the amount of children who are overweight or obese in the world.
